Period Summary

Hog Says

1,459 wave-buoy observations covered all 31 days. Typical wave height was 1.9 ft (10th–90th percentile 1.1–5.2 ft), while mean average of more than one wave period type was 7 seconds (10th–90th percentile 4.4–11.8 seconds). Mean water temperature was 6.6°C (10th–90th percentile 5.8–7.2°C). 12 of 5,800 checked values (0.2%) were excluded by quality control. Across 6 comparable years, mean wave height was the same as the same-month mean of 2.6 ft and mean wave period was above the same-month mean of 6.7 seconds.

About Happisburgh wave buoy

Happisburgh is a Channel Coastal Observatory wave station off the northeast Norfolk coast. It supplies a nearshore North Sea record for one of England's most rapidly changing soft-cliff frontages, where communities, beaches and coastal defences are exposed to frequent erosion.

Its current data source reports wave height, wave period, wave direction, directional spread and sea temperature.
